(Cl. 215-37) i such as rubber, which is itself covered by means v 7Claims.

A phial is now made of a glass bulb which is sealed in a flame and inwhich are kept medical preparations intended to be inhaled, or solutionsfor injection, and which are thus kept aseptic. y A phial-tube is alsoknown for which a special syringe is necessary.

The phials which require a ille for cutting them or breaking thempresent disadvantages such as untimely breakage, defective files,possibility of forgetting the file, etc., and also present the danger ofsmall fragments. of glass being accidentally introduced either forexample in the syringe, or even in the body of the patient.

The phial-tube further presents in addition to the disadvantage of aspecial syringe, the danger of having as a closing means a cap thecentre of which is provided with an orice through which the needlepasses and where in consequence bacteria, germs in the air and dust mustinevitably accumulate.

The present invention overcomes these disadvantages and presents aconsiderable technical improvement. It relates to an improved phialcomprising a metal nonperforated capsule characterized by the featurethat the said capsule comprises at least one thin part intended to bepierced by the needle of a syringe without damaging the needle, thiscapsule covering a member of elastic material comprising at least oneoriiice, the said member being placed on a metal sheet closing theopening of the phial;

The accompanying drawing shows by way of example two forms of embodimentof the device according to the invention.

Figure 1 is a view in axial section of a first form of embodiment.

Figures 2 and 3 are plan views of two members..v

of elastic material.

Figure 4 is a view on a large scale of a metal cap, sealing means andfilter. 1

Figure 5 is a view in axial section of a secon form of embodiment. Y

Figure 6 is a plan view of second form of'embodiment.

Figure '7 is a viewA in axial section of the lsecond form of embodiment,the closure of the phial being traversed by the nozzle of a syringe.

The phial shown in Figures l, 2, 3 and 4 comprises a relatively thinglass tube I provided with a base; the other end of the tube I isprovided with an opening flared in such a way as to form -a circularshoulder. This opening is closed by means of a metal sheet 4 for exampleof tin. applied on the shoulder 3. 0n this sheet is placed a plate 5 ofcompressible material for example of a metal cap 6 for example ofpressed aluminium secured around the end of the tube I.

an orii'lce 1, eccentric or not, is provided through the plate 5; a thinpart 8 is arranged in the central part of the cap 6, this thin part aswell as the orifice 1 and the sheet 4 being intended to be traversed bythe needle of a syringe. The orifice 1 may be replaced by a slot or bytwo slots 9 arranged in the form of a cross.

The wall of the tube I of the container shown, being relatively thick,will break only seldom during the various operations such asdisinfecting, lling, closing, sterilizing, packing and transport towhich the phial is subjected. Before the phial is used, the caps 6 caneasily be sterilized either by means of a llame or a disinfectant. Thecontents of the tube I can be aspirated by means f a syringe, the needleof which can easily perorate the metal cap 6 without being blunted, thesaid metal cap 6 comprising for this purpose a very thin part 8. Theneedle of the nozzle then passes ilrstlythrough the plate ofcompressible material and secondly through rthe tin plate d. Thecontents of the phial can then be aspirated without diiiculty due to thepresence of theoriiice 1 provided in the rubber plate which prevents theformation of a vacuum in the phial which may be capable of preventingthe discharge.

A duid-tight seal of the phial illustrated is ensured due to the plateof compressible material, the phial being thus of the kind termeduniversal type." l

The phial shown in Figures 5, 6 and 7 comprises a closure provided witha metal nonperforated capsule I0, for example of aluminium, fastened orcrimped around a circular shoulder II provided with a tube I2; the saidcapsule I0 provided `with a thin part I4 is secured von a member I3, forexample a rubber washer. The capsule I0 comprises two incisions I5' thedepth of which is less than the thickness of the capsule, theseincisions/ being intended t'o facilitate the subsequent perforation ofthe capsule Ill by the knozzle I5 of a hypodermic syringe IB.

The member I3 which is placed on a tin sheet 42| closing the` opening ofthe phial comprises firstly an orifice 20 opposite .the thin part Ilintended for the passage of the nozzleIS, and secondly an oriilce Il forthe aspiration' of the solution contained in the phial I2 when thecontents are discharged by means of a syringe I8. The orifice I1 of themember I3 is covered with a sterilized filter I9.
